1. How to check if raw syslog data is received in the system? What if it is not received?
In the section for adding data of syslog based devices we have explained how to enable syslog forwarding on the the data sources first and then add that device into KHIKA. When we add a device successfully, we can see the device entry in the “List of Devices” tab. (For this, go to Configure – Adapter – Manage Devices next to that Adapter.)
However if raw syslogs are not received from that device, we get an error while adding the device.
It is recommended to wait for upto 10 minutes before checking its data. To check whether we are receiving this device’s data in KHIKA, go to “Discover” screen from the left menu. Search for the IP address of the device in the search textbox on the top of the screen.
In our example from the image, IP address is “10.2.5.6”. In the search bar in the Discover screen, just enter “10.2.5.6”. This is for showing up any and all data relevant to the device with this IP.
If you can see data for this IP address, the logs are being received into KHIKA successfully.
If not, please check section for adding data of syslog based devices. Both the steps – adding a device in KHIKA as well as forwarding syslogs from that device to KHIKA should be verified again.
2. Why can’t I see any raw data on Discover Screen?
On the Discover screen, you have to choose 2 things to bring up your data :
- Time duration
- Index pattern
Select the required index pattern from the dropdown on the left of the Discover Screen. This selects your data type and whether it is “raw” or calculated “rpt” data. Refer section for help on changing index
Then select the time duration of data you want to see from the time picker functionality on top right. Selecting time window is explained here
If time duration is selected too large, it may severely affect the performance of MARS. We recommend not selecting the data beyond Last 24 hours. Your searches may time out if you select large Time Ranges.
Reduce your time window and try again. It is advised to keep a lesser time window. However on the contrary, if there is no / very less data in the picked time window, you might want to increase your time window from the time picker and load the screen again.
Every dashboard in KHIKA will have multiple devices' data in it. For example, a linux logon dashboard has information about all the linux devices in the "LINUX" workspace say. the name of the relevant workspace is appears before the name of the dashboard.
To see data on the dashboard for only one linux device, you have to select the required device on your Dashboard. There are couple of ways to select an APV on your dashboard :
- Add a filter
- Enter Search query
The following procedure is applicable to all Dashboards.
Steps for Adding a Filter
On each dashboard, there is an option, “Add a filter”. Click on the “+” sign to add a new one. Use the simple drop downs in combination, to create your logical filter query.
faq3.1
faq3.2
The first dropdown is the list of fields from our data. We have selected “server_ip” here. The second dropdown is a logical connector. We have selected “is” in this dropdown. The third dropdown has the values of this field. We have selected one device say 10.13.1.3 here. So now, our filter query is : “server_ip is 10.13.1.3”
Click on Save at the bottom of this filter pop up.
Your Dashboard now shows data for only the selected device in all the pie charts, bar graphs and summary table – everywhere in the dashboard.
The applied filter is seen on top.
faq3.3
To remove the filter, hover on the filter icon on top (selected in red in above figure). Icons appear. Click on the bin icon ifaq3.1 to remove the filter. The Dashboard returns to its previous state.
faq3.4
Please Note : If this is just a single search event, donot follow further steps. If you want to save this search for this particular device with the Dashboard, follow steps given further to save the search.
Click on Edit link on the top right of the Dashboard – Save link appears. Click on Save to save this search query with the dashboard.
faq3.5
The filter currently applied shall continue to be seen on top of your Dashboard. You can remove this filter at any point of time in the future by clicking on the bin icon on your dashboard – as already explained.
Steps to Search and Save
On the top of the Dashboard, there is a text box for search. Enter your device search query for a particular device in this box.
faq3.6
We have entered server_ip:”10.13.1.3” . This is the syntax for server_ip equals to 10.13.1.3. Click on the rightmost search button in that textbox to search for this particular device on the dashboard.
All the elements on the Dashboard shall now reflect data for the selected device.
faq3.7
Please Note : If this is just a single search event, donot follow further steps. If you want to save this search for this particular device with the Dashboard, follow steps given further to save the search.
Click on Edit link above the search textbox – Save link appears. Click on Save to save this search query with the dashboard.
faq3.8
This shall stay with the Dashboard and will be seen every time we open the Dashboard.
To remove the search, select the search query which you can see in that textbox, remove / delete it. Click on Edit and Save the Dashboard again. It changes back to its previous state.
